JOHN D. HALEY, OF WAVELAND, INDIANAL IMPROVEMENT IN FIRE-BACKS FORSTOVES.

Specification forming partof Letters Patent No. 179,551, dated July 4,1876; application filed June 13, 1876.

To all whom it may concern:

Be it known that I, JOHN D. HALEY, of Waveland, county of Montgomery andState of Indiana, have invented certain new and useful Improvements inthat class of devices known as Fire-Backs for Stoves, of which thefollowing, in connection with the accompanying drawing, is a full,clear, and exact description.

Inv the drawing, Figure l is a perspective view of my improved fireback. Fig. 2 is a sectional elevation upon a plane passed through boththe fire-back proper and its aux- Fig. 3 is a rear view, showing the.method adopted of securing the two parts together, and Fig. 4 is aperspective view of a modified form of my device.

The object of my present invention is to provide a fire-back which canbe readily and easily adjusted both as to length and depth, to fit thedifferent-sized fire-pots of stoves, to accomplish which, it (theinvention) consists in certain novel constructions and arrangements ofparts, to be hereinafter more particularly described, and pointed out inthe claims.

A is the portion of the tire-back having its lower portion corrugated,as shown at a, a a 8w. These corrugations facilitate the chipping oft ofthe lower portion of the back in case it be too broad to fitinto thefire-pot-an operation easily accomplished by using the hammer orpinchers. The groovesn a 850., are snfficient in number for all ordinarycases wherein the invention is likely to be required.

Fire-pots of ordinary stoves vary .much more in their length than intheir depth, and

- it is therefore desirable that the fire-back permit the two plates tobe equally narrowed.

Upon the rear of the main section A I cast one or more lugs, l, whichare fitted to receive a key, k, and section B is provided with one ormore slots, S, to correspond with lugs l.

The section 13 having been properly adjusted upon the back to make thetwo together of suitable length, the key is is tightly driven in, andthe two pieces thereby firmly secured together.

This connection is the simplest and cheapest which I have been able todevise, and, being located in rear of the fire-back, cannot becomedamaged by heat until the whole back is destroyed.

I also provide the top extension of the fireback with corrugations f b,&c., to permit that portion of the back .to be chipped off in case it bedesirable to incline it more toward the oven-wall or wall of the stove,as shown at W, Fig. 2. l

At Fig. 4 is shown a modification of the invention, wherein the doubleadjustment is attained by using a series of vertical corruga tions, 0 c,zc., in addition to and for a similar purpose as the grooves a a, &c.

This device is intended to beused in all classes of stoves wherein afirepot is employed, but it is especially adapted for cooking-stoves.When used for this class of stoves I cast a projection, P, upon the faceof the main section, to serve as a rest for the bridge usually foundtherein.

By providing for both the vertical and horizontal adjustments, as aboveexplained, I am enabled to produce a fire-back which may be fitted inplace by an ordinary workman 'without special tools, and as but a singlesize is necessary, it may be manufactured with less expense, besidespermitting the dealers to carry a smaller stock than would otherwise bere quired.

I am aware that the method of chipping off the lower portion of thesupplementary back is not new, having before been described in a UnitedStates Patent, and I desire it understood that I lay no claim thereto;but

Having fully described my invention, what I do claim as new is 1. Incombination with the main section A of the fire back, provided withgrooves a a, 860., the adjustable section B, similarly 1 In testimonythat I claim the foregoing I grooved, as and for the purposes explained.have hereunto set my hand in presence of two 2.
